Petro's hook

What is it?

A simple but effective solution developed by Petro Mhagama, one of MSABI's best drillers, for quickly shortening the chain that doesn't wear out or break. The hook replaces the 17mm bolt that is used to change the chain length, the hook is permanently attached towards the top of the chain, the hook is then hooked through a link lower down the chain thus skipping the links imbetween. The design saves time whilst drilling and by removing waiting times for finding new bolts.
